Hong has 16 cups of rice to make two of the recipes for a potluck dinner.
If he wants to use all of the rice, which of the following should he make?
--Risotto 1/6 cup per serving--
--Pilaf 1/3 per serving--
--Cury 1/2 per serving--

A. 36 serving of risotto and 20 serving of curry

B. 12 serving of risotto and 7 serving of curry

C. 18 serving of risotto and 30 serving of pilaf

D. 24 serving of pilaf and 8 serving of curry

A. is the correct answer.

Step-by-step explanation:

36 servings of risotto at 1/6 a cup per serving equals 6 cups.

20 servings of curry at 1/2 cup per serving equals 10 cups.

6 cups plus 10 cups equals 16 cups and all his rice is gone.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
